Title: An improved method of repairing and refitting ingot moulds, casting plates and the like, more particularly those of large dimensions
IPC: B23P6/04
Filed: 1958-10-29
Abstract: 896,693. Repairing ingot moulds; uniting by fusion. GALVANI, G. Oct. 29, 1958, No. 34750/58. Class 83 (4). A method of repairing and refitting ingot moulds, casting plates and the like comprises the steps of applying an anchoring weld deposit and of applying a filling weld deposit consisting of a material different from that of the anchoring weld deposit which steps are effected while the article being repaired is cold, and in succession. The first step consists in removing the damaged, burnt or oxidized part of the erosion 3 with a cutting electrode, or a chisel, drill, milling cutter or grinder. The cavity 7 is divided into cavities 8, 9 and 10 by refractory partitions 11 and 12 and the repair of these cavities is effected in succession but not at first in contiguous cavities. The repair consists of applying concurrently an anchoring layer 14 of cast iron and a cast iron filling 15 from cast iron electrodes the filling electrode being coated with a mixture of pure carbon powder, sodium silicate and Kaolin. During the repair the mass is kept at red heat and after cooling the partitions 11 and 12 are removed and the gaps filled with metal from the cast iron electrode. In another example the cavity 22 to be repaired is partly filled as hitherto but using non-coated electrodes and the outside is completed with a micro-crystalline cast iron coated electrode to produce a hard and heat-resistant surface 26 (Fig. 5). In a modification for repairing a split 27 in an ingot mould 1 (Fig. G) transverse seatings 28 are cut in the mould for receiving steel plates 31<SP>1</SP> which are inserted hot and attached by weld fillets 32, Fig. 9. On cooling the chambers 30 of the seatings are filled with weld material. The plate, which will always remain under stress, may be protected by a second plate 31<SP>11</SP> (Fig. 11).

Title: Improvements in and relating to devices for forming a continuous sheet of dough and like plastic material
IPC: A21C3/04
Filed: 1953-12-14
Abstract: 742,448. Dough sheeting apparatus. NEUTELINGS, T. R., and NEUTELINGS, W., [trading as INDUSTRIEEN HANDELMAATSCHAPPIJ DE VUURSLAG C. V.]. Dec. 14, 1953 [Jan. 9, 1953], No. 34804/53. Class 87 (2). A device for forming a continuous sheet of dough and like plastic material, comprising a hopper for the dough to be treated and three rollers mounted below the hopper, one being approximately twice the diameter of the other two which are located one above the other, has means for adjusting the positions of the smaller rollers with respect to the larger roller such that for treating hard dough an equal quantity is fed between the upper small roller and the large roller as is discharged between the larger roller and the lower small roller. The peripheral speeds of the large roller 3 and the lower roller 4 are the same, their rotational speeds being suited to this condition by gearing through which they are driven. The upper roller 2, which is ribbed, is gear-driven from the shaft of the roller 4. The shaft 12 of the roller 3 is carried by the frame and the shafts of the rollers 2, 4 are journalled in side plates 11 which are together movable by a link 32 and screw 31, under the control of a handwheel 27 which turns the screw through a worm and wheel 29, 30. This movement of the side plates 11 adjusts the gap between the rollers 2 and 3. The shaft 20 of the roller 4 is supported by a pair of links 42 and is also journalled in blocks 39 which are movable in slots in links 38, mounted at one end on the shaft 12, by a rod 37 threaded through the block and rotated by a worm and worm wheel 35, 36 the worm being rotated by a handwheel 33. For sheeting soft dough the rollers are so adjusted that a chamber 5 bounded by the rollers, side plates and a spacing block 6 is completely filled, the edge of the spacing block 6 stripping dough from the roller 2, except that carried round in its grooves. For sheeting hard dough the roller 2 is adjusted to such a position that an equal quantity of dough is fed between the rollers 2, 3 as is discharged by the rollers 3, 4. Between the rollers 2 and 4 the roller 3 serves as a carrier for the sheet of dough. In order to examine the sheet of dough in the chamber 5 a part 10 can be removed from the spacing block 6. The resulting sheet of dough is stripped from the rollers 3, 4 by knives 8, 9.

Abstract: 1,061,056. Transistor multivibrator circuits. TEXAS INSTRUMENTS Ltd. Sept. 17, 1963 [Sept. 17, 1962], No. 35369/62. Heading H3T. A transistor astable multivibrator has a common discharge path for the cross-coupling capacitors which is alternately switched in parallel with the individual discharge paths. In Fig. 2, when VT2 is non-conducting, capacitor C2 discharges through resistor RB2 and through a diode D2 which is biased to be conducting. When V2T is conducting, diode D2 is cut-off and diode D1 operates similarly for C1. By providing the additional path a rapid discharge and thus high-frequency operation may be achieved without reducing the coupling capacitors to values comparable with the effective base capacitance and without reducing resistors RC1 and RC2 to a value which will heavily saturate the transistors when they are on. Resistor VRt varies the operating frequency and the circuit may be designed to operate asymmetrically. In an explanatory circuit not in accordance with the invention (Fig. 1, not shown), individual additional discharge paths (RT1, RT2) are provided by resistors connected between each base and its respective collector so that they do not provide base current when the transistors are conducting and the discharge path through the diodes is omitted.
